Firefree Coatings has taken another step in passing testing on cardboard shipping containers. On cardboard boxes coated with Firefree 88 and loaded with lithium batteries, the coating was able to contain the battery fire to within the box and not let it expand outward into the additional boxes that made up the total shipping package of multiple sized boxes.

Additionally the testing on the boxes coated with Firefree 88 showed that the temperatures within a single box, or within a larger box containing multiple boxes did not exceed 400 degrees C within the batteries storage box space. The temperature on the cardboard boxes reach a maximum of 300 C within the heavily loaded smaller storage box, with additional temperature readings around additional boxes ranging from 30 C to 160 C within the larger cardboard box container in which multiple, smaller boxes were also placed.
